How to do a kind of transpose

[PauloC]

Hello Experts,

I am a beginner of SAS and need your kind help to find the best way to transpose one table . Any advice will be greatly appreciated.

I have a sample data set as attachment where you can see what i want to do: Thank you very much for your time and help.

First transpose it to a long format and then you can transpose it to a wide format using both old/new and usage of ID and IDLABEL statements.

If you post data as a data step someone can help with the code.

And sometimes a double transpose is needed for extra wide data sets: <- this is what you need.

You can probably get there by using two PROC TRANSPOSE steps. First to convert your current wide struction into a tall structure.  Then a second one to convert it back into the even wider version you want.

proc transpose data=have out=tall;
  by p;
run;

proc transpose data=tall out=wide(drop=_name_) delim=_;
  id _name_ p ;
  var col1;
run;

But why do you think that is going to help you?

For most purposes the TALL structure is probably better. Or even your original semi-wide structure.
